UNITED STATES PATENT Erica.

. STEPHEN P. M. TASKER, OF PHILADELPHIA, PENNSYLVANIA.

ROLLING-MILL.

SPECIFICATION forming part of Letters Patent No. 228,841, dated June 15, 1880.

Application filed October 25, 1879.

To all whom it may concern Be it known that I, STEPHEN P. M. TAS- KER, of Philadelphia, Pennsylvania, have invented an Improved Rollin g-Mill for Rolling and Edging Metal, of which the following is a specification.

0f the accompanying drawings, Figure 1 is a side elevation of an apparatus embodying my invention; Fig; 2, a sectional top plan view of the same and Fig. 3, a perspective detail of the rolls removed from their housing and equipped with guide-teeth constructed according to my invention in two convenient methods.

Similar letters of reference indicate corresponding parts.

My invention relates to that class of rolls which act upon either the flat surfaces or the edges of the product subjected to their operation when the same is a sheet, and which act upon all or either of the sides of other products, such as bars and the like.

The object of my invention is the construction of a mill provided with a pass for feeding and rolling or edging and otherwise truing up and finishing sheets or other forms or products of metal, said pass being essentially composed of what 1 term guideteeth, suitably conformed and combined with rolls, and operating to feed and carry the product to be acted upon in between the rolls to which they are applied without causing the friction incident to the passage of said product in an inclosed and continuous guide, and further operating to prevent the formation of a web or fin upon either face of the product.

Referring to the drawings, A are a pair of rolls, supported with parallel axes in a suitable housing, B. They are suitably driven in any convenient manner, and at such speed as varying products demand. They may be ad justable, so as to be capable of being placed nearer together or farther apart, within the scope, however, of the guide-teeth.

G- are circular collars, adj ustably secured to the rolls, and D are the guide-teeth, which may, when it is desired to make them adjustable, be formed upon, with, or into the collars in any fit method, or else, when it is desired that they should remain invariably fixed, be formed upon'the rolls. P is thepass.

Considered with reference to opposite sets thereof, the teeth mesh in the manner of the leaves of ordinarytoothed wheels, while the planes of the respective opposing and working faces of each set are coincident, whatever may be the position in which the opposite pairs are set, or whatever the angle or position in which the rolls are placed.

The teeth, by their inter-reach, serve to carry and feed the product into and through the pass formed, preventing sheets from buckling and finning upon either of the surfaces exposed to their action. They also hold the product in place and guide it in its transit, and prevent spreading while the rolls are acting upon it.

Mechanically considered, the guide -tecth may be constructed in any convenient way, and of any convenient shape or length, and may be either formed upon or affixed to the collars, or, if desired, one or both sets on each roll may be formed upon the roll.

In the drawings the teeth of the right-hand roll are affixed to the exterior faces of the collars, while those of the left-hand roll are affixed to the inner sides of the collars and extend into the rolls. Many other methods of attachment may of course be resorted to.

In the operation of my device the housing and. rolls may be secured in any desired position, and the products fed in with reference to the position in which the apparatus is placed.

In practice I sometimes arrange my rolls in series connected by guides of a construction invented by me, or by ordinary guides, and I also arrange them either in the same or in different planes, as I see fit, according to the manner in which I desire to har e the product acted upon.

By the adjustment of the collars and rolls the pass may be varied in size or shape. In

all cases, however, the action of the teeth and rolls upon the product is the same, and such as has been hereinbefore described.

Having thus described my invention, I I In testimony whereof I havehereunto signed claim and desire to secure by Letters Patent my name this 15th day of October, A. D. of the United States 1879.

As a device for feeding, guiding, and roll- 5 ing metal products, one or more pairs of rolls STEPHEN P. M TASKER.

suitably placed, mounted, and driven, and v .provided with guide teeth either fixedly or In presence of adjustably applied to the rolls, or to collars or J. BoNsALL TAYLOR, the like upon said rolls, substantially as de- W. O. STRAWBRIDGE.
